nfs:nfs_disable_rddir_cache

Controls
the use of a cache to hold responses from NFS version 2 READDIR
and NFS Version 3 READDIR and READDIRPLUS
requests. This cache avoids over-the-wire calls to the server to retrieve
directory information.

When to Change

Examine the value
of this parameter if interoperability problems develop due to a server that
does not update the modification time on a directory when a file or directory
is created in it or removed from it. The symptoms are that new names do not
appear in directory listings after they have been added to the directory or
that old names do not disappear after they have been removed from the directory.

This parameter controls the caching for both NFS version 2 and 3 mounted
file systems. This parameter applies to all NFS mounted file systems, so caching
cannot be disabled or enabled on a per file system basis.
